4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Stefan Wahren <stefan.wahren@xxxxxxxx> [ Upstream commit 136f55f660192ce04af091642efc75d85e017364 ] As long the bh tasklet isn't scheduled once, no packet from the rx path will be handled. Since the tx path also schedule the same tasklet this situation only persits until the first packet transmission. So fix this issue by scheduling the tasklet after link reset.
